Brand new MP and Tiger

We might be investing in a new Mac Pro soon, and this will come with Leopard. Unfortunately, a lot of software that will be used on it is currently experiencing issues in Leopard (Photoshop CS2 for example). We also have an original Tiger installer DVD (the generic one bought off the shelf, not one that came with a computer).

If it turns out that the applications in question won't work with Leopard, will the new MP's allow me to wipe the HD and downgrade to Tiger? And more's the point - will Tiger actually run on them?

Sorry, should have made myself clearer, I'm talking about a current-model Mac Pro.

Oh, D'oh! Probably my mistake more than yours -- like many here I've got "New Mac Pro New Mac Pro" on the brain. Yeah, you're totally set. No problem at all putting Tiger on a currently-shipping Mac Pro even if it comes with Leopard.

That's great - cheers for the replies And Nugget - I think it was the "new MP's" in my first post that confused things

Ideally, we'd buy CS3 at the same time, but a hastily-purchased Mac Pro + 23" ACD does take quite a chunk out of your back pocket (dying G4 MDD has meant an urgent upgrade), so Leopard might have to wait a bit if CS2 has "issues".

I have a nasty feeling it isn't... on the disk it just says "Mac OS X Tiger 10.4" and "Disc version 1.1" and "Copyright 2005". From memory I think it's something like 10.4.2, but it might be slightly newer.

How much of a problem is that? Is it possible to install using the Tiger installer DVD then download the 10.4.11 update from either the Apple website or Software updater?

Are you sure the new Mac Pro you buy won't be coming with Tiger preinstalled and Leopard dropped in?

No idea. It'll be ordered from the Apple UK online store some time within the next couple of weeks (unlikely to be a BTO, just stock processor, RAM and everything else). Are Apple's stock machines still shipping with Tiger?
